Abstract

Disclosed are a light emitting display device and a method of manufacturing the same, which prevent a lifetime of a light emitting layer from being shortened and prevent occurrence of a turn-on defect. The light emitting display device includes a plurality of pixels each including a transistor having a gate electrode, an active layer overlapping the gate electrode, a source electrode connected to one side of the active layer, and a drain electrode connected to another side of the active layer. The pixels further include a light emitting device having a first electrode, a light emitting layer disposed on the first electrode, and a second electrode disposed on the light emitting layer. The light emitting display device includes a contact hole, and the first electrodes of at least two of the pixels are electrically connected to side surfaces of respective source electrodes or to side surfaces of respective drain electrodes in the contact hole.
